9 ZERO GROUND DISTURBANCE C-RINGSECONDARY CONTAINMENT SYSTEM CANADA 3. BEFORE YOU BEGIN 3. Before You Begin 3.1. Important Installation Notes Check with the local Authority Having Jurisdiction (AHJ) - local, state or provincial, and federal regulatory agencies such as the EPA, AEUB, etc., regarding this product and its intended application prior to installation. If installing outside of the continental United States or Canada, contact the appropriate local Department of Environment or equivalent. Correct installation particularly of support posts is critical to the performance of your system. Plan your site well in advance, including access, capacity, and layout. Containment capacity is based on level walls. If your site slopes, the actual capacity of the containment will be reduced. Have installed capacity confirmed by an engineer. Liquid fertilizer applications require additional capacity in some jurisdictions. The site must be sufficiently level to allow wall sheet assembly without distortion or unsafe assembly conditions, and should provide sufficient drainage around the outside of the ring to prevent standing water buildup without soil erosion. Standing water allowed to remain in the ring will reduce the effective capacity of your system. Regular inspection and specific disposal procedures may be required by local regulations. Local fire codes may require minimum clearances between the ring and tank(s). Steel secondary containment rings, as manufactured by Westeel, are designed for the horizontal containment of fluids only. Prevention of fluid loss through the ground area within the ring (vertical containment) to AHJ regulations will require the use of a suitable impermeable liner. Selection of the correct liner for your application depends on many factors. Consult your dealer, the liner manufacturer, and your local AHJ. Specific Westeel liner suggestions, if made, are based on common chemical properties. It is the owner/user's responsibility to ensure their suitability for a specific application. Testing services are available through liner manufacturer. Liner installation suggestions are outlined in this manual as guidelines only. Any modifications to the installation recommendations provided in this manual must be approved by a qualified professional engineer according to all governing regulations and sound engineering principles. 9

10 3. BEFORE YOU BEGIN ZERO GROUND DISTURBANCE C-RINGSECONDARY CONTAINMENT SYSTEM CANADA 3.2. Important Product Design and Installation Details Fluid Density The standard design of this containment ring is based upon the containment of or external flooding by a gradual release of fluids with densities of 62.4 lbs/ft 3 (1,000 kg/m 3 ) or less, or specific gravity less than or equal to Containment systems may also be used for denser applications such as liquid fertilizer, for liquid densities of up to 83 lbs/ft 3 (1,340 kg/m 3 ), or a specific gravity of Support Posts and Anchoring All containment ring systems require support posts, anchors, or concrete braces to prevent wind damage and reinforce the containment walls against internal fluid pressure. Divider walls installed within the ring must also be supported at standard post spacings, with posts alternately spaced on both sides of the wall Soils Soil conditions and strengths vary widely in different regions. Guidelines are provided for support post piles under different loading and soils conditions, and must be met or exceeded or warranty may be void. Support post and pier recommendations are not designed for submerged soil conditions. It is the owner's responsibility to ensure that soil conditions are sufficiently stable to provide adequate support for support posts and the fluid loads which could bear on the enclosed area in the event of a fluid release. Consult a qualified professional engineer to certify the site soils as suitable, or to recommend remedial action as necessary. Check with local power, gas, & telephone authorities before drilling or excavating to ensure that there are no buried cables or pipes on the site Concrete Specifications All concrete used for piles or pads must have a minimum 28 day compressive strength of 3500 psi (25 Mpa). In some soil conditions a high strength sulphate-resistant concrete may be required. Consult a qualified professional engineer. Reinforcing bar should be ASTM A615 GR. 40 / CSA G30M.12 (300 Mpa) minimum. Re-bar splice lengths should be 15" minimum Wall Penetrations Any holes cut into the wall panels for service needs, etc. must not exceed 8" high x 12" wide. Install additional support posts on both sides of each opening. Seal thoroughly to maintain system integrity Liner Installation General suggestions for sub-base, liner, and protective cover installation are shown in Section 5.5. Site Planning on page 24. Confirm these with your local AHJ, and the liner installer and/or manufacturer. Liner material must be compatible with the product being stored. Liners must be protected from exposure to sharp objects and excessive loads from above and/or below the liner, and over all internal bolts and sharp edges that may come into contact with the liner, is recommended. Provision of adequate slack in the liner to allow for potential liner shrinkage due to thermal contraction in cold conditions is critical to liner performance. Ensure that this taken into account by your installer. These steps will help prevent damage to the liner seams and reduce the potential for product leakage. 10

11 ZERO GROUND DISTURBANCE C-RINGSECONDARY CONTAINMENT SYSTEM CANADA 3. BEFORE YOU BEGIN 3.5. Product Storage Rust on Galvanized Parts 1. White rust forms when moisture is allowed to collect on galvanized surfaces that have yet to develop the durable zinc oxide layer. This zinc oxide layer naturally occurs as the surface interacts with carbon dioxide, and is characterized over time by the dull grey appearance that weathered galvanized surfaces get. 2. Parts that are not well ventilated or well drained can collect water between surfaces and develop white rust. 3. White rust is not a structural concern if its development is stopped in the early stages. A light film or powdery residue can occur after a period of heavy rainfall or a short time of improper storage. If white rust has started to develop, separate parts and wipe off any moisture. Next, using a clean cloth, apply a thin layer of petroleum jelly or food-grade oil to the entire part. 4. If moisture is left on parts, this white rust can become more aggressive and turn into red rust. Red rust can cause degradation in the material and become a structural concern. Any parts that have red rust should be replaced immediately. Storage Guidelines Keep all bundles dry before assembly of the bin. Start assembly as soon as possible. Do not lay bundles on the bare ground. Raise all bundles 6 to 8 off the ground on wood blocks or timbers. (See Detail A in Figure 2 on page 11.) Store curved wall sheets hump-up. (See Detail A in Figure 2 on page 11.) All other bundles material should be placed so that they are well sloped to promote good drainage. (See Detail B in Figure 2 on page 11.) Roof sheets must be elevated at least 12 at the small end of the sheets. (See Detail B in Figure 2 on page 11.) Temporary storage can be provided by erecting a simple framework supporting a waterproof tarp. (See Detail C in Figure 2 on page 11.) All bin boxes, ladder boxes and hardware boxes should be stored inside. These are not waterproof, and will deteriorate in normal weather conditions, allowing moisture to contact the parts inside. Figure 2. Product Storage A B C D If Parts Become Wet 1. If parts become submerged or wet, the bundles should be opened as soon as possible, sheets or material separated and dried. Keep separated until assembly. Brace parts properly so as to avoid damage or injury from material falling when in storage. (See Detail D in Figure 2 on page 11.) 2. Any boxed parts that become wet should be dried and stored in a new box that is free of moisture. 11

12 3. BEFORE YOU BEGIN ZERO GROUND DISTURBANCE C-RINGSECONDARY CONTAINMENT SYSTEM CANADA 3. In addition to wiping down wall sheets, a food-grade oil can also be applied with a clean, lint-free cloth. This will assist in preventing any further moisture from contacting the galvanizing on the steel. Due to safety concerns with installation and use, Westeel does not recommend the use of oil on other parts such as roof sheets and safety ladders Important Notes In order to maintain your wall sheets in good condition separate sheets and allow air circulation between them. Store sheets in a dry place. Do not store sheets with sheet ends pointing upwards. To keep an even pressure on walls, the bin must always be unloaded from the centre. Contact local power officials for minimum power line clearance. See Section 3.2. Important Product Design and Installation Details on page 10 for materials that can be stored. Tighten all bolts to the recommended torque settings. Do not locate grain bins close to high buildings, which might cause snow to fall onto or build up on the roof of the grain bin. Consider future expansion and allow space for loading and unloading of the bin. Your dealer and local government agricultural consultants can help you plan your storage system for maximum efficiency General Information and Requirements 1. The system is intended for secondary containment of a gradual release of fluids with a specific gravity of 1.34 or less (i.e. fluids with densities of 86.0 pounds/cubic foot, or 1340 kg/cubic meter, or less). The configuration of the system is dependent on wall height, and on the specific gravity of the intended fluid as provided in the following table. Table 1. Number of Braces Required for Various Wall Heights and Liquid s Specific Gravity Wall Height (in) Specific Gravity (SG) of Contained Fluid # of Braces 22 SG </= braces for every 2 wall panels 33 SG </= braces for every 2 wall panels < SG </= braces per full wall panel 44 SG </= braces per full wall panel < SG </= braces per full wall panel 57 SG <= braces per full wall panel Note This system is not intended for primary containment. 2. For liner requirements see Section System Liner Considerations on page For site and soil requirements see Section System Site Considerations on page For assembly requirements see Section System Installation Considerations on page This system was not designed to resist external flooding. 6. Seismic loading was not considered in the design of this system. 12

13 ZERO GROUND DISTURBANCE C-RINGSECONDARY CONTAINMENT SYSTEM CANADA 3. BEFORE YOU BEGIN System Site Considerations 1. Check with your local Authority Having Jurisdiction (local, state or provincial, and federal regulatory agencies such as the EPA, AEUB, etc.) regarding this product and its intended application prior to installation. If installing outside of the continental United States or Canada, contact the appropriate local Department of Environment or equivalent. Correct installation is critical to the performance of your system. 2. Plan your site well in advance, including access, capacity, and layout. Containment capacity is based on level walls. If your site is not level, the actual capacity of the containment will be reduced. Have installed capacity confirmed by an engineer. Standing water allowed to remain in the ring will reduce the effective capacity of your system. Regular inspection and specific disposal procedures may be required by local regulations. Local Fire Codes may require minimum clearances between the ring and primary containment tank(s). 3. The site must be sufficiently level and free of obstructions to allow wall sheet assembly without distortion or unsafe assembly conditions. There can be no high or low spots that result in suspended or bridged support pads along the length of the walls. 4. A packed base is required. The soil must be capable of supporting the brace/pad systems. This requires soil with a soil to soil static friction coefficient of 0.5 or better. Literature suggests that a packed sand base will consistently provide this requirement. Physical tests conducted with 4 or better, of a packed sand base, consistently satisfied this requirement. If in doubt about the characteristics of soil conditions on site, consult a qualified professional engineer to certify that the site soils are suitable, or to suggest remedial action as required. Table 2. Friction Coefficients for Sand Type of Sand Loose Dense Uniform sand, rounded particles Well-graded sand, angular particles Sandy gravel Silty sand.51 to to.67 (Derived from Soil Mechanics 2 nd Edition, R. F. Craig) 5. The soil conditions must be maintained throughout the life of the system. The soil supporting the pads cannot be allowed to erode away. Therefore site specific factors such as drainage, weather patterns, wind patterns, annual climatic factors, and other erosion factors must be considered in the installation. Depending upon the presence of these factors, there may an ongoing maintenance requirement to insure that site conditions remain consistent with the requirements of the system, throughout the life of the system. 6. Depending on system configuration, the resistance to external wind loading varies. The difference depends upon the presence, or not, of 4 of sand evenly spread on the top of the liner, inside the wall, such that the pads, and the intervening spaces, are completely covered. Another consideration depends upon the presence, or not, of 4 of sand completely covering the pad on the outside of the wall. Increasing the depth (i.e. weight) of the sand will improve the wind loading characteristics. The values presented in the following table are the corresponding allowable reference velocity pressures (q) (kpa), as defined in the National Building Code of Canada (NBC). Values of q (kpa) for selected locations in Canada are provided in the NBC. 13

Allowable Reference Velocity Pressures Allowable Reference Velocity Pressures q (kpa) 2 Pad Systems Wall Height (in) C-Ring Structure Only With 4 Sand Inside With 4 Sand Inside and Outside Allowable Reference Velocity Pressures q (kpa) 3 Pad Systems System Installation Considerations 1. All pads must be fully engaged in the underlying soils. All voids within the pad must be filled with soil. There can be no bridging, or suspended pads along the length of the wall. 2. A packed base is required. 3. The liner attachment to the wall must be as per the installation instructions. Along the straight wall sections of the oblong or rectangular systems, the liner/wall connection should be consistent, free of puckers and folds, and free of high and low spots. In the event the liner must carry load, the transfer of load should be uniform along the entire length of the wall. The liner should not be bunched, or bagged along a straight wall, rather a smooth consistent curve between the vertical wall section and the horizontal flat section is required. Some puckering and folding is inevitable against the rounded ends of an oblong system or in the corners of a rectangular system and is acceptable in these areas only. 4. The friction characteristics between the steel pads and the protective geo-textile cloth, and between the cloth and the liner, can be improved upon by spreading a film of sand between these components. This is encouraged System Liner Considerations 1. The liner forms an integral part of the structural integrity of this system. Ultimate liner selection and installation is the responsibility of others. However the liner must be at least 30 mil and have tensile strength characteristics equal to, or greater than, 66 ppi stress at yield (not to be confused with stress at break). 2. Any welds in the liner must have a bonded seam strength equal to or greater than 66 ppi. If not, there can be no welded seam, running parallel to a straight segment of the wall, within seven feet of the wall. 3. The liner must maintain its physical properties for the life of the system. Therefore, its aging and weathering characteristics, compatibility with materials present, etc. must be considered in the selection and installation of the liner Concrete Pad Considerations This system can be readily adapted for installation to a concrete pad. The support pads are not required and the braces can be attached directly to the concrete. The design of the pad and the attachment of the system to the pad, is the responsibility of others. 14

Spacing (not shown in the diagram on this page): Straight panels for 22" and 33"petroleum applications (s.g. < 1.0) and 22 fertilizer applications (s.g. </= 1.34) use a 75 spacing (3 pads / 2 full panels). Straight panels for 44 petroleum applications (s.g.<1.0) use a 56 1/4 spacing (2 pads / full panel) Straight panels for 33 and 44 fertilizer applications (s.g. </=1.34) use a 37½ spacing (3 pads / full panel). Straight panels for 57" petroleum applications (s.g. <= 1.0) use a 37 1/2" spacing (3 pads / full panel). For best fit and appearance, install curved panels inside straight panels as shown in Figure 13 on page 27. Oblong system ends require full support bracing if the diameter exceeds 78 ft. Use the pad spacing specified in Figure 13 on page 27 For systems 78 ft and less, in diameter, 2 braces per end are required. These braces should be located at 60 degrees from the end of the curved portion. Some diameters (15', 21', 27', & 33') require a half-panel on each end to complete the semi-circle. 28

Before installing the liner, at the wall panel seams, place two 3 long strips of butyl tape in the valley at the bottom liner clamp location as shown in Figure 15 on page 30. a. Make sure the strip is butted up against the edge of the lapping wall panel. b. Apply a continuous butyl tape strip around the entire cell. Figure 15.

When installing the liner, ensure the liner transitions smoothly from the wall sheet (vertical) to the ground (horizontal) as shown in Figure 16 on page 31. a. Place a geotextile cloth between the liner and the steel pad to protect the liner from sharp edges. b. Alternatively, the steel pad can be wrapped in the geotextile cloth. c. After the liner is fully installed and all the clamps are securely in place, trim away the excess liner, using the top edge of the liner clamp as a guide. 30

33 ZERO GROUND DISTURBANCE C-RINGSECONDARY CONTAINMENT SYSTEM CANADA 6. APPENDIX 6.2. Recommended Bolt Assembly When tightening bolts, tighten the nut on the bolt until a snug-tightened condition has been achieved. A snug-tightened condition is defined in Specification for Structural Joints Using ASTM A325 or A490 Bolts (Research Council on Structural Connections: June 2004), which states: The snug-tightened condition is the tightness that is attained with a few impacts of an impact wrench or the full effort of an ironworker using an ordinary spud wrench to bring the connected plies into firm contact. A properly tightened bolt will compress the sealing washer noticeably. All assembly crew members must be made aware of this requirement, and must know how to achieve a snug-tightened condition using common binbuilding tools. It is important that the bolts in the vertical wall sheet seams are tightened enough to squeeze the caulking and bring the wall sheet surfaces into firm contact with each other. This is especially important to monitor when installing bolts in temperatures approaching -10 C (14 F). The following table shows the minimum impact gun torque capacity necessary to achieve a snug-tightened condition for bolts used in the assembly process. Table 5. Recommended Impact Gun Torque Values Capacity to Achieve Snug-Tightened Bolts Recommended Torque Capacity Bolt Diameter Bolt Grade Grade Mark in-lb ft-lb N-m 1/4 Grade /16" Grade /8" Grade /16" Grade /2 Grade /8 Grade /4 Grade For proper sealing, do not overtighten the wall seam connections. Sealing is not critical on upright splice connections; these connections should be tightened securely to prevent loosening. Hold the bolt head securely when tightening the nut to prevent damage to the sealing washer. Important ALWAYS TIGHTEN THE NUT, NOT THE BOLT! Avoid bin assembly at temperatures below -10 C (14 F) if possible. Erection in low temperatures does not ensure strong, well sealed connections. Do not substitute bolts in place of those supplied by Westeel. 33
